TABULATING ATTACHMENT FOR TYPEWRITERS.

Specification of Letters Patent.

Patented June 28, 1921.

Application filed November 20, 1919. Serial No. 339,463.

To all whom it may concern:

Be it known that I, MARVIN (irARRETT, a citizen of the United States,residing at Pensacola, in the county of Escambla and State of Florida,have invented certain new and useful Improvements in TabulatingAttachments for Typewriters, of whlch the following is a specification.

My invention has for its object the provision of a tabulating attachmentfor typewriters which will be efficient in operation and easilymanipulated and which may be applied to a typewriter at a cost which isnot prohibitive. The invention seeks to provide a tabulating attachmentby which a form containing any number of columns within the capacity ofthe typewriter may be filled without requiring a separate adj ustment ofthe tabulator after it has once been set. A further object of theinvention is to provide an attachment which will adapt the typewriter toa variety of forms without requiring the removal and replacement of theattachment or readjustment of the same, and a still further object ofthe invention is to provide a tabulating attachment which may be easilyset to accurately arrange statistics in columns. The stated objects andother objects which will hereinafter'appear are attained in such amechanism as is illustrated in the accompanying drawings, and theinvention resides in certain novel features which will be particularlypointed out in claims following a detailed. description.

In the accompanying drawings, I have illustrated a portion of anUnderwood typewriter, indicatedat 1, having my tabulating attachmentapplied thereto, but it is to be understood that this showing is forconvenience of illustration only and is not restrictive in any wayinasmuch as the attachment may be applied to any standard make oftypewriter without substantial change in form or construction. Thetypewriter frame illustrated is provided at its back corners with posts2 and. in carrying out my invention. 1 mount in the said posts the endsof a rock shaft 3 which may slide as well as rotate in the 'said postsand constitutes the main member of the stop bar carrier. Standards -.land 5 rise from this rock shaft 3 at intermediate points of the same andthe stop bar 6 is supported upon the said standards. The standard 4, asshown most clearly in Fig. 4, is provided at its upper end with acrosshead 7 disposed obliquely with respect to the rock shaft 3 andprovided at its extremities with upstanding lugs or stops 8 while thestandard 5 is constructed at its upper end with a crosshead 9 disposedat a right angle to the axis of the shaft 3 and in the same horizontalplane with the crosshead 7 but the said crosshead 9 is provided at itsfront end with an upstanding lug 10 from which a retaining'plate 11extends rearwardly to overhang the crosshead and rest upon the uppersurface of the stop bar when the parts are assembled. The rear end ofthe crosshead 9 is free of upstanding projections, as shown clearly inFig. 4, but upon the said crosshead, near the rear end thereof,Ipivotally mount a latch 12 having an upturned hook 13 at its rear endadapted to engage the rear edge of the stop bar so as to retain the samein position upon the crosshead. This latch is constructed with adepending handle or finger 14 against which a spring 15, secured to thestandard 5, bears so that the latch will normally be held in its upperposition. The stop bar is preferably oblong and rectangular in plan viewbut its upper surface is arcuate or convex, as shown at 16, except atthe end engaged by the retaining plate or keeper 11, said convex surfacebeing formed on an arc concentric with the rock shaft 3 so that when thestop bar carrier is rocked the surface of the stop bar will remain inconstant relation to the counterstops, as will presently appear. Thestop bar is of such width that its front and rear edges will fitrespectively against the front and rear lugs 8, as shown in Fig. 3. andin the front edge of the stop bar near the left hand end thereof I formrecesses or notches 17 and 13 which are respectively adapted to engagethe lug 10 at the front end of the crosshead 9, the purpose of whichconstruction will hereinafter appear. In placing the stop bar inposition it is first disposed obliquely relative to the rock shaft 3 sothat its right hand end may be passed between the lugs 8 after which itis swung around so that its left hand end will ride over the latch 13and onto the crosshead 9, the notch 17 or the notch 18 engaging the lug10 and the latch 13 springing up intoengagement with the rear edge of.the stop bar to lock the stop bar in position upon the carrier. \Vhen itis desired to remove the stop bar for any reason, pressure is applied tothe finger or handle member 14 to overcome the spring 15 and release thelatch whereupon the stop bar may be readily swunggearwardly about thestandard 4 as a center and withdrawn from between the lugs 8 as will bereadily understood.

The stop bar is capable of both a rocking and an endwise slidingadjustment and these adjustments are effected through manipulation of akey at the front of the typewriter and adjacent the right hand side ofthe bank of typewriter keys. Depending from the rock shaft 3, is an arm19 having a crank 20 at its lower end extending toward the right handend of the haft. This arm 19 is shown as alined with the standard 4 butit will, of course, be understood that the exact position of the arm isnot material and it may be disposed at any point where it will properlyperform its allotted functions. Se cured to the side of the typewriterframe at the bottom thereof are a pair of brackets 21 and a singlebracket 22. The brackets 21 consist each of'a bar having openings 23therethrough and provided at one end with an upstanding lug 24 throughwhich a. fasstood that as the bar 25 is slid forwardly or baclm'ardlythe crank 20 will be set in motion and the arm 19 correspondingly swungso that the shaft 3 will be rocked to set the stop bar in a desiredposition. The front end of the sliding bar 25 rests upon the bracket 22which is substantially U-shaped, having upstanding lugs 29 at its ends,and upon the outer side of the bar 25 is formed a rack 30, as clearlyshown in Figs. 5 and 8.

The front end of the bar 26 also rests upon the upper surface of thebracket 22 and the lugs 29 at the ends of said bracket serve as guidesfor the slide bars in the, operation of the same, the outer lug 29 alsofurnishing means whereby the bracket may be secured to the frame of thetypewriter. The bracket is provided midway its ends with openings 31either of which may receive the lower end of a stem 32 depending fromthe key 33, the openings being separated by a web 34, as clearly shownin Fig. 6. A hinge bracket 35 is secured to the front of the typewriterframe and a lever plate 36 is hinged or pivoted to said bracket, as.shown in Figs. 5 and 6, the rear end of the said lever plate beingprovided with a vertically disposed sleeve 37 to receive the stem 32 andalso having a llOI'lZOIltilLJlOtCh 38 to accommodate a pinion 39. vhichis manipulated by the sai'd stem It will be noted that the pinion isprovided witha central opening having inwardly extending lugs 40 on itsWalls and the key stem 32 is provided with channels or grooves 41 in itssides which are adapted to receive the said lugs whereby the stem mayslide through the pinion but cannot rot-ate inde endently of the pinion.The sleeve 37 furnishes a bearing for the key stem and the pinion mayengage the rack 30 upon the slide bar 25 or the rack 42 upon the innerside of the slide bar 26 accordingly as the lever plate 36 is swung toone or the other side. When the pinion is so engaged, the rotation ofthe key 33 and the stem 32 will cause the pinion to act upon the engagedrack and thereby slide the corresponding bar forwardly or rearwardly, aswill be readily understood. The stem may be raised so that its lower endwill clear the openings 31 when the pinion is to be shifted from side toside but after the pinion has been properly shifted, if the stem belowered so that its end will engage in an opening 31, the desired rotarymovement may then be imparted to the pinion without causing it to swingaway from the engaged rack, and to further hold the pinion in the saidadjusted position I provide a dog consisting of a leaf spring 43 securedto the under side of the bracket 22 at the front edge thereof and havinga lip 44 at its free end projecting upwardly past the front, edge of thebracket to engage against the side of the lever plate 36, as shown inFig. 7, and thereby hold it in the position in which it may be set. Theform and strength of the spring should be such that it will normallyhold the lever plate against movement but will readily yield whenpressure is applied to the plate through the key 33 and stem 32. Anindex rod 45 rises from the slide bar 25 and is constructed at its upperend with a'pointer or finger 46 playing over an index plate 47 which issecured to the front of the typewriter frame adjacent the bank of keysand is provided with a forwardly and rearwardly extending slot 48through which the said index rod may pass and in which it may play. Ascale is displayed upon the index plate 47 adjacent the slot 48 and thisscale corresponds to the number of longitudinal rows ofstops providedupon the stop bar 6 so that the numeral to which the index 46points-will designate the row of stops which is in position to beengaged by the counterstop upon the typewriter carriage, as willpresently be more fully set forth.

From the slide bar 26 an index rod 49 rises to pass through and play ina longitudinal slot 50 formed in the index plate 47 and upon the upperend of this index rod 49 is a double pointer 51 which at one end pointsto'the same graduations with which the index 46 cooperates and at itsopposite end points to and cooperates with a scale indicating thedenominations to which the stops have been adjusted. The slide bar 26terminates adjacent the back of the typewriter frame and at its rear endis equipped on its outer side with a rack 52 which is engaged by asegmental gear 53 carried by the lower end of a vertical rock shaft 54which is mounted in suitable bearings 55 upon the side of the typewriterframe At the upper end of the shaft 54, I provide a second segmentalgear. 56, which engages a rack 57 formed on the front side of a settingblock 58 which is fitted upon the rock shaft 3 and may be, in someinstances, formed integral therewith. In the illustrated embodiment ofthe invention, the block 58 at one end rests against the standard 4 andat the opposite end against a collar 59 through which'a set screw 60 isinserted to bear upon the rock shaft and thereby secure the collar tothe shaft so that while the shaft may rock in the block it cannot moveendwise unless the block be likewise moved. Obviously. when the bar 26is moved forwardly or backwardly the shaft 54 will be rotated and anendwise movement imparted to the block 58 and the shaft 3 through theoperation of the segment 56 and the rack 57. To aid in holding the bar26 in the position in which it may be set, a series of teeth or stops 61may be provided upon the under side of the bar to be engaged by a.spring pawl 62 secured upon the typewriter frame or to one of thebrackets 21 and a duplicate of this arrangement may be provided to holdthe bar 25 against undue endwise movement.

To reduce wear, the ends of the pawls may be equipped with rollers asshown in Fig. 8.

In the operation of the device, a stop upon the stop bar 6 is engaged bya counterstop upon the typewriter carriage and to hold the stop bar andits carrier against movement under the shock of this engagement, Iprovide the rack 63 on the under side of the block 58 and also provide aholding pawl 64 to engage said rack or stop and hold the block and thecarrier firmly against cndwise movement. The holding pawl 64 isillustrated in the form of a lever fulcrumed upon the typewriter frameand having its rear free end playing between said frame and a bracket65, secured to the same, the rear end of the pawl forming a toothadapted to readily enter between adjacent teeth of the rack 63 andsecurely hold the same. The front end of the pawl .is pivoted to a link(36 which has its lower end pivoted to a key lever 67 disposed betweenand somewhat above the bars 25 and 26 and having its front end carriedupwardly, as shown at 69, and terminating in a lip 69 fitting to thestem 32 immediately below the key 33 and above a collar 70 secured uponthe said stem. The rear end of the lever 67 is fulcrumed upon thetypewriter frame and the connection with the link 66 is in advance ofthe fulcrum so that, when the key 33 is depressed, the lip 69 willfollow the movement and the key lever 67 consequently swing downwardlyand pull upon the link 66 to rock the pawl G4,.the rear end of whichwill be thereby caused to engage the rack 63. The link 66 extends abovethe pawl 64 and has its upper end pivoted to a forwardly extending arm71 on the front side of a combined brake bar and trip bar which is provided at its ends with trunnions orpintles 72 journaled in suitablebearings upon the. typewriter frame. This combined brake and trip bar isdisposed upon th typewriter in advance of the rock shaft 3 and consists,in

the illustrated construction, of a flat bar 73 having depending portions74 at its ends, the trunnions 7 2 extending from the lower ends of thedepending portions 74 and the arm 71 projecting from one of saidvdepending portions so that the trunnions form the center about which theseveral parts swing. A trip 75 issecured to and depends from the bar 73and is provided at its lower end with a forwardly projecting lug or lip76 which is adapted to bear upon the escapement trip lever usuallyprovided upon the typewriter whereby when the bar 73 is rocked thetypewriter escapement will be released and the carriage permitted tomove. The carriage of the typewriter is indicated conventionally at 77.A leaf spring. 100 arranged between the arm 71 and the top of thetypewriter frame holds the trip bar in.

its normal position and. returns it to that position after it has beenrocked.

A rod, indicated at 78, is ordinarily found upon the carriage of anUnderwood typewriter and, in applying my attachment to that make ofmachine, If utilize this rod as a support for the counterstops whichcooperate with. the stops on the stop bar 6. .in open substantiallyU-shaped frame TS) is provided with ears 80 which are loosely engagedupon the said rod 78 between stop collars 81 whereby the frame may swingabout but cannot slide longitudinally of the rod. A spring 82 is coiledaround the rod 78 between the ears 80 and has one end secured to the rodand its other and secured to one of the ears whereby the spring tends tohold the frame away from the stop bar. A back plate 83 connects the cars30 and from one end of said backplate a hanger 84 depends, a roller 85being carried upon the rear side of said hanger 84l adj acent the lowerend of the same in position to run upon the front face of the trip andbrake bar 73 as will be readily understood and as indicated by thedotted lines in Fig. 11. The carriage stops or counterstops are mountedin the outer or rear portion of the frame 79 and are carried by a rod 86inserted through the sides of the frame 79 and an intermediate web 87disposed midway the sides and parallel therewith, the said web 87serving to connect the rear end of the frame with a bridge plate 88 nearthe frontend thereof. Two counter-stops are provided, as shown at 89 and90, and each of said counterstops is provided at its ends with lips 91,the rear lips being adapted to rest upon the rear end of the frame 7 9while the front lips are engaged by leaf springs 92 which are securedupon the bridge plate 88, as shown clearly in Fig. 10. it will bereadily understood, upon reference to Fi s. 10 and 11, that the springs92 tend to liff the inner or front ends of the counterstops and therebyhold the outer or rear ends thereof lowered but will readily yield topermit the counterstops to pass over an obstruction and the rear end ofthe frame 79 forms a support for the counterstops and prevents thembeing swung downwardly to such an extent that they will not properlyengage the stops. Each counterstop is also provided near its rearevtremity with a depending tooth 93 audit will be noted, upon referenceto Fig. 1, that the said depending teeth have their under edges beveledin opposite directions, this arrange ment permitting one counterstop toride over the stops and the other counterstop to engage the stopsaccordingly as the carriage is moving in one or the other direction. Thecounterstops are fitted loosely upon the pivot pin or bolt 86 andbetween each counterstop and the adjacent outer side of the frame 79 acushion spring 9-1 is coiled around the said pin or bolt. If thecounterstops were fixed upon their pivots, when either counterstop wasbrought into engagement with a stop it would remain in a fixed relationto the said stop so that wheirthe escapement mechanism was againoperated the cou'nterstop would again be brought into engagement withthe same stop and the carriage would not be permitted to move. T hearrangement illus trated and described, however, avoids this conditioninasmuch as when the counterstop is brought against the stop it willyield slightly to the impact and the coacting spring 94 will be slightlycompressed. As soon as the frame 79 rises to release the counterstopfrom the stop, the spring 9% will expand so that the counter-stop willthen be projected slightly over the stop, and if it be then againdepressed it will strike the top of the stop and will ride on the sameinstead of impinging against the end or side thereof as before. v

The stop bar 6 is provided with sockets or openings 95 in its uppersurface which are arranged in longitudinal and trans erse rows, asclearly shown in Fig. 3, and it will be readily understood that anydesired number of longitudinal rows may be provided but the transverserows will be limited in number by the length of the line which may beprinted upon the typewriter. These columns or rows of sockets will benumbered from front to rear or from rear to front of the stop bar, asindicated at 96, to correspond with the scale upon the index plate 4700-operating with the pointer a6. Stops 97, which are preferably in theform of a narrow plate having prongs 98 on oneedge, are

"engaged in the sockets 95 at such points as may be necessary to conformto the arrangement of columns to be printed and these stops will projectabove the surface of the stopbar so as to be engaged by the counterstop89 or the counterstop 90 accordingly as the carriage is moved in one orthe other direction. It will be noted that I have shown the stops'asprovided with three prongs or teeth 98 which are to be engaged inadjacent openings in the proper column of tlie stop bar 6, the provisionof a plurality of prongs or teeth preventing twisting of the stops fromtheir proper operative positions. While I do not restrict myself to theillustrated details of the stop and the stop bar, it may be noted thatthe form of stop shown presents its edge to the counterstop and a thinstop will effectually withstand the impact of the countcrstop, and thesame number of stops can be accommodated on a narrower bar than isfeasible with the usual construction inasmuch as the stops are presentedside to side transversely of the stop bar.

In the drawings, I have illustrated eight rows of sockets or openingsextending lengthwise of the stop bar 6. The stops obviously may beengaged in the sockets at any point along any of the rows and by providing stops at several different points along any one row I adapt thetabulator to any one form upon which data is to be transcribed.()bviimsly, therefore, the illustrated stop bar may be set up toaccommodate eight different forms and it will not be necessary for theoperator to change his machine or change the adjustment of the tabulatorwhen his work involves the use of a variety of forms. It is frequentlynecessary to transcribe data into a plurality of different forms upon asingle sheet and my attachment permits the operator to do such workwithout delay. It is also possible to provide for a large number ofcombinations of different forms inasmuch as the stop bar is readilyremovable and a stop bar having a different arrangement of stops may bequickly substituted for one which has been in use.

When the tabulator is to be used, the stops are engaged in the propersockets of the stop bar so that they will conform to the arrangement ofcolumns into which data is to be transcribed after which the key 33 isshifted to bring the pinion 39 into engagement with the rack 30 and isthen rotated so that the bar 25 will he slid backwardly or forwardly.When the pointer 46 has been brought into alinement with the indiciadenoting the proper column or row of stops upon the stop bar. theoperator will know that the stop bar is then in such position that itwill stop the carriage in position for printing in the first column uponthe sheet and the successive stops upon the stop bar in the rowindicated upon the index plate will cause the carriage to stop inpositions to permit printing in the successive columns upon the sheet.When the bar 25 slides forwardly or backwardly, the standard 27 will belikewise moved and the shaft 3 rocked through the action of the crank 20and the arm .19, as previously stated, and such rocking ot' the shaft 3will bring the proper row of stops 97 into the path of the counterstopsrelatively fixed upon the carriage. After the proper row of stopshasbeen brought into the path of the counterstops, the pinion 39 is shiftedinto engagement withthe rack 42 so as to slide the bar 26 forwardly orrearwardly. The movement of the bar 26 will be transmitted through thesegment and the shaft 54 to the segment 56 so that an endwise movementwill be imparted to the rock 89 and 90 which are shaft 3 through therack 57 and the block 58. This movement of the shaft 3 will, of course,carry the stop bar 6 endwise and the stop 97 will be shifted relative tothe decimal printing point so that the first character printed by thetypewriter after the carriage has been shifted will represent adenomination corresponding to that indicated by the index 51. in theadjustment indicated in Fig. 8, the machine has been adjusted for use inconnection with a sheet having an arrangement of columns correspondingto the adjustment of the stops in the fourth longitudinal row of socketsof the stop bar and to print the first character in any column in theposition to represent ten thousandths if the notch 18 be engaged withthe portion 10 of the keeper, or four spaces past the point for whichthe stop is set if the notch 17 be engaged with the member 10. After thestop bar has been adjusted, the key 33 is depressed so that the frontend ofthe key lever 67 will be swung downwardly and a downward pullexerted upon-the link 66 which will swing the holding pawl 64 intoengagement with the rack 63 so that the stop bar will be held firm andwill not move under the impact of the carriage, and simultaneously withthis movement of the holding pawl 6% the brake and trip bar 73 will berocked forwardly so that the arm 84 will be swung forwardly and thecounterstop frame 7 S) swung downwardly, the counterstops being therebylowered into position to engage the stops. its the trip bar 73 swingsforwardly, the trip 76 will release the escapement lever of thetypewriter and the carriage will then at once more under the action ofthe spring drum in the. usual manner, said movement of the carriagecontinuing until one of the counterstops engages the first stop. Thenumber to be transcribed may then be written, after which the key 33will be again depressed and the carriage will move. until thecounterstop thereon engages the second stop, the carriage being therebybrought into position to permit printing in a second column, and thisoperation may be repeated until all of the data has been transcribed.Obviously, the movement of the carriage is in the nature of a jump and.unless retarded, will tend to damage some of the parts under the shockof stopping. I, therefore, provide upon the type writer carriage a blockor pad of leather, rubber, or other material, indicated at 99, whichwill be engaged by the trip bar 73 when the latter is swung forwardly torelease the escapeme nt and the movement of the carriage will be therebyretarded so that the impact of the counterstop upon a stop will not beso abrupt as to cause breakage.

The stop bar will be held against endwise movement upon its carrier bythe engagement of the lug 10 at the front end of the crosshead 9 in thenotch 1'7 or the notch 18,

and either of these notches will be engaged accordingly as it is desiredto stop the carriage before the stop 97 reaches the printing point orbring the carriage to a stop after the printing point has been passed.It will be understood, of course, that each longitudinal row of socketsupon the stop bar represents one form and that the spacing of stops ineach row corresponds to the widths of the columns in the formrepresented by that row. It only one forml appears upon the sheet to befilled in, the stops may be ar ranged with one stop in each longitudinalrow of sockets upon the stop bar so that the desired'adjustment oi thestop bar may be effected by manipulating the slide bar 25 and the slidebar 26 may remain at rest throughout the operation.

lVith my device the printing point may be at either side of the stop.The notches 17 and 18 are spaced aparta distance equal to nine printingspaces of the typewriter so that by shifting the stop bar in itscarrier, the position of the stop, relative to the typewriter carriagemay be shifted nine spaces. Referring to Fig. 5 of the accompanyingdrawings, it will be noted that the pointer 46 carried by the slide isopposite the numeral 4 upon the index plate and that the double pointer51 is opposite the same nu- -mel'al and also opposite the legend l0Thous The word legends on the index plate are read in connection withthe pointer 51 only when lug 10 is engaged by the notch 18. Assume astop 97 to be in the fourth longitudinal row of sockets in the stop barand in the fortyfourth transverse row. that is 44 points or spaces fromthe beginning of a line of writing. If the key 33 be now depressed, thecarriage will move and will stop with the printing point at are. Now, itthe pointers 46 and 51 be left undisturbed and the stop bar be shiftedto bring the notch 17 into engagement with the lug 10, the step 97 willbe shifted nine spaces to the left on the machine and the printing pointon the paper shifted nine spaces to the right, the pointer 51 being thenread in connection with the scale of word legends. In certain classes ofwork, it is desirable to be able to jump the carriage from zero to anypoint or space on the line scale without the trouble of setting thestops, and this result may be accomplished by putting one stop at 10 inthe first longitudinal row of sockets in the stop bar, another stop at20 in the second row, another stop at 30 in the third row, etc, the lug10, of course, being engaged by the notch 17.

'If it be desired to jump the carriage to 24,

for instance, (twenty-four spaces from beginning of line) the key 33will be manipulated so that the pointer 46 stands at 2 and the pointer51 at 4 upon the index plate, after which the key will be depressed torelease the escapement in the manner previously described. The notches17 and 18 may, of course, be otherwise spaced and the range of the indexplate correspondingly varied.

' My tabulating attachment is especially advantageous by reason of thecapability of the stop bar to be adjusted longitudinally relative to thecarriage of the typewriter and this advantage may be amplified byincreasingthe number of notches in the edge of the stop bar so thatinstead of merely two notches arranged as illustrated and previouslydescribed there should be an extended series of notches arranged apart adistance equal to the spacing of the letters of the typewriter. Itfrequently happens that after the stops upon the stop bar have been setto correspond with the verticallines printed on'a form, the form will beinserted in the machine a few spaces to the right or the left of theexact position and it several carbon copies are being made it is verydiiii cult to adjust the paper in the typewriter carriage so as to bringthe printed forms into exact coincidence with the stops withoutdisarranging the forms and as a result the writing on the-carbon. copieswill be out of line with the writing on the original. With my invention,under surh circumstances. the stop bar may be shifted longitudinally therequired number of spaces to the left or to the right so that the stopson the bar Will be brought into strict alincnient with the ruling on theform. hloreover, it is sometimes desired .to print a series of subtotalsof a plurality of columns of figures without setting up a separate rowof stops for the sub-totals and this end may be attained by simplyshifting the bar longitudinally the required number of spaces toward theleft after listing the several items and before printing the sub-totals.The stop bar carrier will, of course. be constructed with a lug or otherstop of suitable form'to engage the notches in the stop bar.

It. will be readily noted that I provide for ,the adjustment of thestops to accommodate the arrangement of columns upon the form to befilled and also to eilcct the necessary denominational adjustment of thedevice through the manipulation of a single key and the same key servesto release the carriage to bring it into the printing position. it willbe noted that the stop bar can be instantly released or removed from itscarrier and another stop bar substituted therefor, and when in positionupon the carrier, the stop bar will be effectually held against endwisemovement relative thereto so that the action of the typewriter will bepositive and certain, and it will also be noted that the device willoperate with equal facility Whether the carriage is moving in one or theother direction and, consequently, it the work is such, that an equalnumber of entries is not to be made in all of the columns, the carriagemay be moved past those columns in which no entries are to be made andneed not be returned entirely across the frame of the machine when nodata is to be put in the first column. The device is not complicated inits operation nor in the construction or arrangement of its parts and itis, therefore, not liable to get out of order and will prove eiiicientin use at all times.

It is to be understood that I do not limit myself to the exactconstruction and arrangement of parts shown in the drawings and hereindescribed inasmuch as various changes may be made in the details withoutinvolving any departure from the principle or scope of the invention asthe same is defined in the appended claims.

Having thus described the invention, what is claimed as new is:

1. A tabulating attachment for typewriters comprising a stop barprovided with a plurality of sockets arranged in longitudinal andtransverse rows, stops selectively engaged in said sockets, counterstopsupon the typewriter carriage to engage said stops, and means for rockingthe stop bar and shifting the same longitudinally to bring a selectedstop into operative position.

2.
